#c_lang#driver#flash#jedec#jedec_sfdp#qspi#sfdp#sfdp_flash#spi_flash#universal_driver **SFUD** is an open-source library that drives many SPI/QSPI Flash chips from brands like Winbond and Macronix. It auto-detects chip specs via the **SFDP** standard or a built-in table, letting you read, write, erase, and init with simple APIs after easy config. This helps you avoid risks from Flash shortages or upgrades, boosts software reuse across projects, cuts dev time, and enables tools like programmers—saving effort on varied hardware. https://github.com/armink/SFUD
